What you can do
Save & Unpack Mac DMG File Data on any Windows System
Use this free DMG extractor to save and unpack Mac DMG file data on any Windows system. No Mac required — validate and prepare DMG disk images in your browser, then unpack with 7-Zip or similar on Windows.
Extract Data from Read Only and Compressed DMG Files
Extract data from read-only and compressed DMG files. The tool supports standard UDIF DMG format and validates read-only and compressed disk images so you know which files are ready to unpack on Windows.
Option to Add Multiple DMG Files One After the Other
Add multiple DMG files one after the other. Build a list of disk images, then run extract/validate on all of them at once. Remove individual files from the list if needed before processing.
Provides Different Search Options to Find Data in Disk Image File
Search options to find data in your disk image list: search by file name or by status (success/fail). Filter the results table after completion so you can quickly locate specific DMG files or see only succeeded or failed items.
Unpack DMG Emails Along with the Associated Attachments
When your DMG contains email files (e.g. .eml, .msg) and attachments, unpack the disk image with 7-Zip or your preferred extractor on Windows to get emails along with their associated attachments in one place.
Display Both Success and Fail Count Report After Completion
After processing, the tool displays a completion report with both success count and fail count. See at a glance how many DMG files were valid and how many failed, plus a detailed table with status and notes for each file.
